react創建元件的三種方式分別是什麼

function myConponent(props) {
	return `Hello${props.name}`
}

var myCreate = React.createClass({
	defaultProps: {
		//code
	},
	getInitialState: function() {
		return { //code };
	},
	render:function(){
		return ( //code );
	}
})

class InputControlES6 extends React.Component {
	constructor(props) {
		super(props);
		this.state = {
			state_exam: props.exam
		}
		//ES6类中函数必须手动绑定
		this.handleChange = this.handleChange.bind(this);
	}
	handleChange() {
		this.setState({
			state_exam: 'hello world'
		});
	}
	render() {
		return( //code )
	};
}

function App(props) {
	function handleClick() {
		props.dispatch({ type: 'app/create' });
	}
	return <div onClick={handleClick}>{props.name}</div>
}

class App extends React.Component {
	handleClick() {
		this.props.dispatch({ type: 'app/create' });
	}
	render() {
		return <div onClick={this.handleClick.bind(this)}>{this.props.name}</div>
	}
}

import React, { useState } from 'react';
function App(props) {
	const [count, setCount] = useState(0);
	function handleClick() {
		setCount(count + 1);
	}
	return <div onClick={handleClick}>{count}</div>
}

class App extends React.Component {
	state = { count: 0 }
	handleClick() {
		this.setState({ count: this.state.count +1 })
	}
	render() {
		return <div onClick={this.handleClick.bind(this)}>{this.state.count}</div>
	}
}
